sans amp BDDI with a gk 1001 rb 2, yay or nay?? opinions please.

Hey all, I've been using my new amp the GK 1001 RB II since I got it last month and I've also picked up a Neo 410 to run with it. Now I have for a long time pushed a fender bassman with a 400 watt yorkville bassmaster and I suplimented that rig with the sans amp bass driver di and had great results with that. Now that I've got this rig though, I'm really really loving the tone of the GK sans sans amp. But after playing this amp and cab rig for a little I feel like I'm nit getting enough tone and or "edge" to my sound while playing louder in a jam setting. What are your guys opinions on this? Any of you familiar with these particular pieces of equipment together enough to form a strong opinion on this amp and cab with or WITHOUT the sans amp bddi?
